To all whom 2'22 may concern.

' Be it known that I, Crninrins EsMAnrAN, a CItlI-ZQll of the United States, residing at Paterson, in the-county of Passaic and State of New Jersey, have invented certa n new and useful Improvements in Demountable Rims of which the followin is a s ecific a- 7 b 7 rim consisting of two parts disposed cir cumferentially of the tire and having a radial flange to be held by a plurality of fastening and "lockingfbolts so designed as r to obviate their removal when one of the sections is separated in removing a tire.

Another and very important object of the invention is the provision of a novel and improved locking bolt which is adapted in one of its positions to' be moved outwardly of one of the sections of the rim so as to be disengaged from its locked position, and rotated so that one of the sections of the rim may be removed.

Another and continued object of the invention is the construction of a demountable rim of the class above set forth which is extremely simple in construction, highly efficient in operation and use, strong and durable, consisting of a minimum number oil-parts and otherwise capable of being manufactured at an extremely low cost whereby its commercial possibilities are greatly enhanced.

I attain the above objects andothers in the accompanying drawings, showing a preferred form of the invention, wherein,

Figure 1 is a view in side elevation of a vehicle wheel embodying my improvement.

Figure 2 is a sectional view showing the combination rim and one of the locking bolts.

Figure 3 is a side view showing the dif ferent positions of the locking bolt.

Figure 1 is a view taken from the opposite side of the bolt shown by Figure 3 and Figure 5 is a sectional. view of the rim head 21 showing one of the locking tending through the telly.

bolts as ex lieierringnow to the drawings, wherein lnre reference characters designate corre sponding parts thro views, 5 designates the tire and 6 the telly of ing its outer face cut ughout the several usual type of clincher a ve ncle wheel havaway as at 2a about the outer periphery of the telly to point flCljEtCQIlt the inner per1phery so as-to define a shoulder on which the rim may rest.

The rim itself consists of a main sec tion 9 having its outer edge 10 bent in the formof a curve so as to engage the bead of the usual clincher type tire site edge 11 extends ferentially vertically of the run and is designed to while the oppo and circumabutthe vertical flange 12 of the complementary outer section similarly formed with to engage the tire proper.

Referring in particular to Figure 2, it

willbe observed that t of the IlJl which is a curved portion 13 he felly is partly cut awayasat 15 and attached to the inner side of the-flange 11 of the rim section 9,

l haveprovided substantially triangular attaching plate 16, in and secured thereto b fastening elements as the form of an ear y rivets 17 or other shown. The bottom portion of the triangular plate 16 is preferably provided with a squared opening 18 which forms a locking means for the square portion 19 of my novel and improved lock bolt,

the shank 20 of which extends through suitable semi-circular recesses formed in the bottom of the vertical the rim sections. The

flanges .11 and 12 of outer end of the lock bolt is preferably formed with an enlarged which abuts and locks the outer section of the rim when the nut 22 on the threaded end 23 of the lock e'ned, threaded end of the bolt is tightit being obsewed that the nut and lock bolt are seated within the recess or cut out portion 2% of the telly somewhat removed from riphery thereof.

the outer pe- In addition to the above locking means, the respectwe sections of the rim are secured by a plurality of additional elongated .lock bolts 27, thethrea are disposed within th ded ends 28 of which e threaded sleeves 29 extending through suitable apertures 30 within the telly. A washer 31 may be applied to the base of the the sleeve if desired to of the latter to form a felly over the end of prevent dislodgement neat finish.

It will be thus observed that my novel and improved locking feature for the sections of the demountable rim are such that the same may be maintained on the felly at all times while the outer section of the rim is removed when replacing a tire and thus prevent the loss of the locking element whichhas been found to be an objectionable feature in many types of sectional rims. In other words, by loosening the nut 22, the square portion 19 I of the shank20 may be moved outwardly of the fastening plate 16 so that the head 21 of the lock bolt may be moved to the dotted line position shown by Figure 3 so that the sec-' stood that the invention is not limited to any particular form of construction in the parts, except in so far as such limitations are specified in the subject matter being claimed.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is 1. A wheel rim comprising two sections,

flanges formed on the respective sections,

neeaaas substantially triangular attaching plates secured to the inner face of one of the sections, said plates having squared sleeves, lock bolts held by the squared sleeve portions of the plate for securing the respective sections together, said lock bolts being movable outwardly thereof to permit one of the sections to be removed.

2. A wheel rim comprising two sections, flanges formed on the respective sections, substantially triangular attaching plates riveted to the inner face of one of the sections, each of said plates having a squared sleeve portion in the bottom thereof, a locking bolt for each squared shank portion of the plates, said locking bolt having squared shank and enlarged head for securing the said sections of the rim together and adapted to be moved outwardly thereof to permit of the separation of thezsections without removing the bolts.

3. A wheel rim comprising two sections, flanges formed on the respective sections, attaching plates secured to the inner face of one of the sections, each of said plates having a sleeve. a' lock bolt cooperatingwith each sleeve for securing the respective sections together, said bolts being'movable outwardly to allow one of the sections to be removed from the other.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES ESMARIAN.
